RAILWAY TIE.

Application filed October 24, 1923.

To aZZ whom it may concern:

Be it known that I, J AMES CAREY DAVIS, a citizen of the United States, and a resident of Hinsdale, in the county of Du Page and State of Illinois, have invented a certain new and useful Improvement in Railway Ties, of which the following is a specification.

This invention relates broadly to railway rail supports, and more particularly to improvements in railway ties, more especially to the provision of an improved composite railway tie which is characterized by the features of rigidity of support, durability, simplicity and altogether improved efficiency in use.

The principal objects and advantages which characterize this invention reside in the provision of an improved railway tie; the provision of an improved railway tie of metallic construction; the provision of an improved metallic foundation railway tie; the provision of an improved railway tie including a metallic supporting element and a non-metallic rail support; the provision of improved means for supporting a railway tie including a metallic base, non-metallic rail supports, and means for fixedly retaining said supports in said tie; the provision of an improved composite railway tie which may be manufactured at low cost.

This invention is furthermore especially characterized by the provision of improved means for detachably connecting a metallic railway tie and a non-metallic rail support, so that renewals of the rail supports may be facilely accomplished by one man, for instance, the track walker, and without the necessity of removing the entire tie from the position which it occupies normally; the provision of an improved composite railway tie including a metallic support which gives the desired weight and rigidity, and a nonmetallic rail support which permits of insulation of the rails of a railway track and at the same time affords the desired resiliency, thus preventing the transmittal of shocks due to the travel of a'train thereover, and thereby increase the life of the tie.

The foregoing and such other objects and advantages as may appear or be pointed out as this description proceeds, are attained in the structural embodiments illustrated in the accompanying drawings, in which:

Serial No. 670,485.

Figure 1 is a side elevational view of a portion of a railway tie constructed in accordance with this invention, showing a rail in position thereon;

Figure 2 is a plan view with the rail and its support removed;

Figure 3 is a view similar to Figure 2, showing the rail and its support in position;

Figure 4- is an end elevational view looking at the left hand end of Figure 1;

Figure 5 is a vertical sectional view taken on the line 55 of Figure 1, looking in the direction indicated by the arrows;

Figure 6 is a vertical sectional view of an alternative form of the device shown in Figure 1 Figures '2 and 8 are elevational views of further alternative forms of the invention;

Figure 9 is a vertical sectional view taken on the line 99 of Figure 7 and Figure 10 is a vertical sectional view taken on the line 1()10 of Figure 8.

Referring now more particularly to the drawings and first to the device illustrated in Figures 1 to 5, both inclusive, 1 provide a base member, generally designated 5, constructed of metal, preferably soft cast steel, and including a medial channel portion 6 having the bottom wall 'I and side walls .8.

The bottom 7 extends throughout the entire tie, and while only one end of the tie is shown and described, it will be understood that the opposite end of the tie is substantially identical with that shown. The base wall 7, for the purposes of drainage and in order to lighten the tie without sacrificing strength, is provided with openings 9 in the end portions 10 and openings 11 in the medial portion of said bottom wall.

The tie is provided near its opposite ends with a pair of pockets, one only of which is shown here, designated 12. The pocket 12 is formed by the provision of a transverse vertical wall 13 defining the outer end of the pocket and, in the present instance, the side walls or flanges 8 are increased in height as at 8 and 8 the walls 8 and 8 being of substantially the same height as the end Wall 13.

The walls 8 and 8 are provided with complemental lugs 14, 14 and. 15 and 15. As shown, these lugs, are arranged complementally opposite on the Walls of the about midway of the height of said walls.

The lugs thus form means for supporting the wooden block 18 and also for preventing rising of the block in the pocket when a train passes over the tie.

In order to secure the block 18 against endwise displacement, the arrangement and dispos tion of said block in the said pocket is such that one end of the block abuts the end wall 13 for preventing outward displacement of said block, and the walls 8 and 8 are provided with openings 2121, preferably located below the plane of the lugs 14 and 15 whereby a standard rail spike 22 may be driven into the block through each of said openings. There have been four openings provided and it will be obviout that two or more spikes may be inserted anddriveninto the block. Where necessary additional openings may be provided, but for ordinary service four spikes will serve to effectually retain the block.

The bottom wall 7 at the pocket 12 is provided' with drain openings 23 23, and the end wall 13 in each case is provided with an elongated opening 24 whereby a crow bar or similar instrument may be inserted for driving the block out of a pocket when replacement is desirable or necessary.

A railway rail 25 has its base 26 resting upon the upper surface of the block 18, said block preferably extending above the upper margins of the walls 8 8 and 13 so that the 'rail will not come in contact with the metallic tie; Screw spikes 2727 of the conventional type are driven into the block and serve to reta'n the rail in position thereon, said spikes being of sufficient length preferably to extend below the planes of the lugs 14: and 15 so that in the event that the block, in service, should split, the screw spikes will serve to hold the parts of the block together until replacement may be made. As shown in Figure 3 the screw spikes 27 are preferably staggered, so that the stra n will be evenly distributed upon the block.

Referring now to Figure 6, a construction similar to that of Figure 1 is illustrated, the pocket 12 being open at the bottom as well as at the top and having an end wall 13 and side walls 9 only one of which latter is shown. The walls 9 and 13 are provided with lugs 28 and 29, respectively, and these lugs seat in recesses formed in the ends and sides of the wooden block 30.

In this instance the block is slid into position similarly as the block 18 and the lugs 31 are bent downwardly to retain the block, said lugs being formed integrally with the walls 9"-. In order to afford additional means for preventing displacement of the block, a transverse bolt 32 extends through the walls 9 and abuts the inner end of the block. It will be obvious that the bolt 32 may pass through the center of the block as will appear in the alternate forms of the invention shown in Figures 7 to 10, inclusive, and it will also appear that the bolt might be employed in the form of the invention illustrated in Figures 1 to 5, inelusive.

Referring now to the device shown in Figures 7 and 9 the metallic tie includes the medial channel portion 33 having its side walls increased in height as at 3 1 and 35 to form, with the end wall 36, a pocket 37 which is adapted to receive the block 38, which is formed preferably of wood. I

The upper edges of the walls 34 and 35 are bent inwardly to provide horizontal flanges 3939 wh ch engage the cutaway portions 10&0 of the block 38 and thus prevent upward displacement of said block.

Endwise displacement of the block is prevented in one direction by the end wall 36 and in the opposite direction by the transverse bolt e1, one only of said bolts be ng shown. It will be understood, of course, that there may be a plurality of the bolts provided if desired, and it will also appear that spikes may be employed here similarly as those employed in the device of F igure 1.

Suitable drainage openings 42 may be provided in the bottom of the tie and this tie may also be lightened in construction in the same way that the tie shown in Figure 1 is lightened.

The invention shown in Figures 8 and 10 is similar to that shown in Figure 7 with the exception that the walls 34 and 35 are provided with recesses and 4-1- in their upper margins for accon'unodation of the rail carried by the block 41-5.

The block is mounted in a pocket having an end wall 36 connecting the s'de walls 3 1 and 35, and the recesses 43 and 1 1 afford extensions 1646 and 17l7 bent to form overlying flanges 18 which engage the top of the block 45 and prevent its upward displacement.

Similar to the form of the invention shown in Figure 7, endw se displacement of the block outwardly is prevented by the wall 36 and similarly displacement in the opposite direction is prevented by the transverse bolt 11.

It will be observed that in the forms. of

ill)

low

the invention shown in Figures 1 to 6, inclusive, the lugs on the vertical walls out the pocket serve to prevent any shearing stress on either the retaining spikes 22 or on the bolts for a similar purpose, the base of the tie and the flanges shown in the forms of Figures 7 to 10, inclusive, relieving the retaining bolts of any vertical shearing stress.

It will be observed that in all of the forms of the invention herein shown anddescribed replacement of the wooden block may be readily accomplished by one man and that it is unnecessary to remove the tie from the road bed when such replacement is being made. Furthermore the employment of wooden blocks as shown results in a great saving in upkeep of the road bed and also permits of utilizing old railway ties of wood which now must be in most cases discarded.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent is:
